Build and load on F5

Co- worker has run into a problem where pressing F5 or start a debug, it does not build and deploy. As a result he cannot do any debugging: breakpoints, single step etc. Why would that be ? We are using teams and he updated to latest and now this is happening

What does the TinyCLR output window show? There any info on what is happening.

Time-out. We have team repository issues here. what co-worker is experiencing is probably related

Is it happen after updated?

If so then you need to check all nuget up to date or not anyone is missing.
